An abnormal, rounded, solid lump above, within, or under the skin that is larger than a papule is called what?

The term that accurately describes an abnormal, rounded, solid lump above, within, or under the skin that is larger than a papule is a nodule. A nodule is typically defined as a small, solid mass that is palpable and can vary in size, being larger than a papule, which is a small, raised bump that is generally less than 1 centimeter in diameter.

While a cyst is a closed sac-like structure that may contain fluid or semi-solid material, it does not necessarily refer to a solid lump. A tubercle is a small, rounded projection or protuberance; however, it is often associated with specific conditions like tuberculosis and may not commonly describe a lump as broadly as a nodule does. A papule, as noted, is indeed smaller than a nodule and does not meet the size criteria specified in the question.

Thus, the best answer is nodule as it encapsulates the characteristics of being a solid mass larger than a papule, fitting the criteria laid out in the question.
